Most Important Android App for Lawyers

Supposea developer wanted to put time and effort into developing an Android app for lawyers. Now, suppose that developer wanted your input as to the most important app for lawyers. What app would you tell the developer to create?

Now is your chance. I may be in the middle of such a project, but I need your opinion and assistance as to where we should focus our efforts for this first app. Also, I’d like to know whether you’d support some sort of crowd-funding or Kickstarter program.
